RESPOOLING 'DEVICE FOR MUSIC-ROLLS.

Specification of Letters Patent.

Application tiled December 18, 1907. Serial No. 407,025.

To allwhom fit may concern:

Be it known that I, GEORGE HowLnT'r DAVIS, a citizen of the UnitedStates, residing in the town of Vest Orange, county of Essex, and Stateof New Jersey, have invented certain new and useful Improvements inRespooling Devices for Music- Rolls; and I do declare the following tobe a full, clear, and exact description of the same, such as will enablethose skilled in the art to which it pertains to make, construct, anduse the same.

My invention relates to devices for respooling perforated music rolls ofthe character and kind used upon so-called automatic or player pianos.In the manufacture of music rolls of this character the rolls of paperto be perforated are fed into the perforators in layers frequently asmany as sixteen-ply, that is to say, sixteen rolls of paper have theirends inserted into the perfor-ating machine, and the sixteen rolls areoperated upon simultaneously. If the sixteen-ply were immediately woundup in a single sixteen-ply roll, the paper would become so distorted andbuckled as to render the individual rolls useless. It is necessary,therefore, that the complete gang of sixteen rollsshall be re-spooled orre-wound into individual rolls.

I will now proceed to describe this speciiic mechanism forlning myinvention.

Figure 1 is a side elevation of the complete structure. Fig. 2 is aplain view partly in section. Fig. 3 is a detached View of the feedroller locked.

The structure is composed of the supporting frame 1, upon the upper sideof which and near one of its longitudinal edges are mounted the twosemicircular spindle supports 2 and 3, secured to the corners of theframe in any convenient or desired manner.

Pivotally carried between spindle supports 2 and 3 are the severalspindles 4, there being in the example illustrated sixteen of suchspindles, which project forwardly or toward the front side of themachine and over-hang the main portion thereof, as illustrated in Fig.2.

Between the semicircular supports 2 and 3 and secured to each individualspindle is a pulley 5, so arranged that all of the pulleys lie in thesame vertical plane. Mounted upon the top of the frame 1, near one endthereof is the shaft 6, such shaft carrying upon its outer end afly-wheel or pulley 7,

and near its inner end the pulley 8, which is I with a drive pulley soas to be driven bv means of belt power. Located substantially in thecenter of the circle formed by the two spindle supports 2 and 3 are thetwo tension pulleys 10 and 11, the pulley 10 being mounted in fixedbearings 12 upon the upper side of the frame, while the pulley 11 ismounted upon a pair of swinging arms 13, located on the inner face ofthe upper members of the frame 1. These arms are held Linder springtension by means of the spring 14C one end of which is secured to theouter end of the arm 13, while the other end is secured to the framemember 1.

In order to hold the pulleys 10 and 11 separate during the process ofthreading up the machine, I provide the pawl 15 upon the inside of theframe, said pawl having a pair of notches to engage the shaft of thepulley l1, as clearly indicated in Fig. 3. Upon the right-hand side ofthe frame as indicated in Fig. 1, I mount a table 16, extending from theedge of the frame beneath the tension roller 10, and provided with theadjustable guides 1'7'at its edges.

At the outer end of the table and secured to the edge of the frame,'asindicated in Fig. 1, -I secure the roller racks, such racks com risinthe two arms 18. havin a plu-- rality of spindles or rollers 19 mountedtherein. At the opposite side of the frame 1, I mount another inclinedtable 20, such table being so located as to cover the shaft 6, and thusprotect the same from contact with the music rolls.

If desired, a belt tightening device, such asillustrated in Fig. 1, at21, may be ro# vided to take up the-slack in the belt 9 heretoforereferred to.

In the use of my improved re-spooling machine, the perforated musicrolls in the form inwhich they come from the perforating machines are inracks or trays, such as that illustrated at 22, the combined series ofrolls being held together by means of the ordinary paper clips and lyingloosely folded in such racks 22. When ready for spooling the upper oroutside end of the bunch of perforated paper 23 is carried up andthreaded over and under the several spindles 19, whence it is carriedacross the table 1G between the adjustable guides 17 and beneath theroll 10, it being understood that the ends are carried between the rolls10 and 11 while the roll 11 is held away from the roller 10 through thepawl 15. The combined ends of the rolls are then carried forward andlaid upon the table 2O when each one is taken up separately and carriedover to the right, as shown in Fig. 1, and given a turn or two aroundthe first spindle at the right. The second layer is then taken and ivena turn or .two upon the second spindle and the third to the .thirdspindle and so on until the entire number of .layers of paper arestarted upon the spools. Vhen so started the completion of the spoolingis effected by the rotation of the shaft G by the crank upon the endthereof.

In the spooling of perforated rolls of this character I have found thatit frequently happens, from one cause or another, that one of the layersof paper will begin to wind a little vmore rapidly than the others. Ifsome means were not provided for maintaining a uniform tension in thatportion of the several layers of paper 23 lying between the spindle andthe tension rollers 10 and 11 there would result a buckled and crinkledeffect in those particular layers of paper having the least tension. Ihave found, however, that in arranging the individual spin dleshorizontally, and collectively, in a semicircle with the belt 9 lightlycontacting the periplieries of the several `pulleys 5, should unduetension exist in any one or more of the layers, then the belt would slipover the corresponding pulley until the tension would be equalized inall of the several layers during the said winding process. It is thisslip of the belt resulting in the proper regulation of the tension thatconstitutes the successful operation of the machine.

When the bunch of paper is completely wound, the rolls are taken offfrom the several spindles, when they are ready for the next step intheir process of completion and a new tray full of unwound rolls isprepared for re-spooling in the manner hereinbefore set forth.

In order to facilitate the starting of a layer of paper upon thespindle, I provide each of the spindles with diametrical notches 24 toreceive corresponding pins upon a crank 25, such crank being detachablefrom each of the spindles and successively applied thereto for thepurpose of starting the end of a layer upon the corresponding spindle.

In order that the belt may have a uniform bearing upon the activespindles 5 at the ends of the supporting frames 2 and 3, I prefer toinsert two terminal pulleys 26, so that the belt or band 9 will have nogreater area of contact upon the terminal pulleys 5 than upon theintermediate pulleys. It will be readily seen that if the belt or band 9passed directly from the drive pulley 8 to the terminal spindle pulleys,there would be agreater area of contact between such band and saidpulleys resulting in a reduced tendency to slip under tension of theterminal rolls.

I believe that I am the first to produce a re-spooling device for musicrolls or other multiple layers of paper of the character heretoforedescribed, wherein provision is made for uniform tension in the severallayers by means of a slip belt, and I, therefore, desire to claim such adevice broadly.
